DH works full time, I work part time (3 days a week). On my days 'off' I have our 2 year old at home and collect my 4 (nearly 5 year old) from school at 3pm.
I do 100% of the mental load at home - car insurance, home insurance, holidays, holiday clubs/organising childcare, remembering stuff for school, organising DC's clothes, Christmas presents etc.
In terms of household stuff I do the majority (but our house is still pretty chaotic - never seems to be tidy, always have washing to etc. so not claiming I am on top of this!) but my DH will usually cook. When we are both at home we share looking after the children.
What is a fair division of the mental load / house hold chores given I am part time?
I think I am doing too much and it's irritating because if I drop something / forget something it doesn't get done (doesn't even get thought about!) e.g. in half term 'I' forgot to cancel the milkman when we were on holiday!
